Comparing with cylinder and single thread profile, it has a good primary stability.An obvious superiority can be seen when it used
for low density sclerotin.Meanwhile micro taper and irregular trapezoid thread could spread out the stress from the implant and
the jawbone in order to keep a physiological balance.
It won't be fractured due to the overload of the jawbone and implant fatigue and gives it a less stress so that the jawbone
shrinks and increase bone resorption.
